Abstract
In this work, a temporomandibular joint prosthesis system is designed in order to be manufactured and implanted. A computer tomography study of a patient with bone cancer and temporomandibular ankylosis was used. The specific design also considered a local socket to replace the mandibular fossa. The manufacturing of the system used stainless steel (AISI-316L). Mechanical evaluation and numerical testing were done using ANSYS code and PTC CREO Parametric 3.0, while in the biomechanical reconstruction, SCAN IP software was used. The fixation of the prosthesis in the patient is an important requirement and the structural behavior is studied using the finite element method (FEM). In order to design and personalize the implants, quick prototyping printer systems (ABS and PLA) were used, while for the manufacturing process, stainless steel 316L was considered, in order to get low costs. As a result of this research, the chewing process of the patient will be performed.
